Alvin A. Schaed/er I INVENTOR.

BY udflwuyfim United States Patent Filed Mar. 27, 1961, Ser. No. 98,679 4 Claims. (Cl. 30-133) This invention relates to certain new and useful improvements in means for picking up, gathering and disposing of hair while being clipped by a barber and pertains, more specifically, to a vacuum line or conduit wherein the intake end is cooperatively connected with a specially constructed hair intake or induction nozzle, the discharge end of said conduit being communicatively and operatively connected with a suitable vacuum source having a container or any equivalent means for collecting and trapping the disposable hair.

The preceding general idea and hair disposal procedure has been a barber shop problem for some time. Persons conversant with it are aware that manyinventors have explored this field of endeavor and have come up with a number of proposed solutions but for one'reason or another their eiforts seem not to be worthy of endorsement, acceptance or widespread adoption and use. It follows that the instant invention seeks to provide ways and means which are capable of accomplishing what is desired by manufacturers, retailers, barbers and other users.

To the ends desired, consider first the fact that the barber must not be hampered in freedom of handling and using the clippers at hand. Manifestly, any arrangement which hinders the barbers skill and action will meet with resentment and will result in objections too numerous to dwell upon. So, with this contingency in mind the instant invention makes available a simple, practical and acceptable means to suspend the clippers so that anticipated difficulties can be overcome. Therefore, and to begin with novel easy-to-handle suspension means is provided. Briefly, this means comprises a hanger embodying a rigid suspension member having an upper end provided with means for attaching said upper end to an elevated stationary support so that said member is hung vertically and rigidly, a rigid suction arm swivelly mounted at one end on said member, said arm being disposed in a horizontal plane, a flexible hose communicatively connected to the other end of said arm, a hair and air induction nozzle carried by said hose, an electric hair clipper connected with said nozzle, and a suction line communicatively joined to said one end and adapted to be connected with a place of deposit for accumulated hair clippings.

The flexible hose is attached to the clippers at a 60 angle on a swivelled arm to allow the barber to operate the clipper by holding the same in his customary way but without also having to hold the hose. The flexible hose is 1% inch, inside measurements, which allows hair of any length to pass through without clogging. The 1% inch inside measurements of the flexible hose attached to the induction nozzle- 7 high and 1 /4" wide--provides suflicient suction-current of air to carry away all of the cut hair.

Another aspect of the concept has to do with hair clippers embodying customary cutting heads at one end of a handle-equipped body, an elongated tubular hair intake nozzle mounted atop said body and having an intake end in close proximity to and aligned with the blades on said heads, said nozzle being provided with a discharge neck, said neck adapted to permit asuction hose to be communicatively joined thereto, and baffle means mounted in the passage of said nozzle and cooperable with the hair intake end of said neck.

The invention also is directed to the nozzle by itself, that is, in the sense that it is a ready-to-use attachment ice which lends itself to use on and in conjunction with electric hair clippers which are currently in use. Briefly the attachment is characterized by a tubular nozzle rectangular in cross-section and defining a hair and air passage, the forward end of said passage being open, one wall of said nozzle having an opening and a hair disposal neck registering the with said opening, said neck being disposed at an oblique angle relative to the long axis of the nozzle and serving to permit the attachment thereto of a suction hose, means carried by said nozzle for mounting the same on a surface of the aforementioned body portion, and a. baffle mounted in said passage and located for associated cooperation with the intake end of said neck.

Then, too, it will be noted that the flexible hose is attached to the nozzle by way of an appropriately angled neck and the construction and arrangement is such that the suction induced draws air through the clipper motor housing or handle thereby keeping the motor cool and easier for the barber to handle.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the ac.- companying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a view in elevation which diagrammatically shows barbers quarters including a barber chair and other facilities and shows, what is more important, the overall vacuum system including the clippers and nozzle mounted atop the same;

FIGURE 2 is a plan view showing a fragmentary portion of the body or handle of the clippers and detailing the improved suction nozzle, the hose being omitted;

FIGURE 3 is a view in section and elevation and at right angles to FIGURE 2 and which serves to show the construction and arrangement of the nozzle;

FIGURE 4 is a section on the line 4-4 of FIGURE 3; and

FIGURE 5 is a view in perspective of thenozzle by itself.

With reference first to FIGURE 1 the letter A designates a chair, B a basin, C a mirror on the wall, D the ceiling being denoted at E. The aforementioned hanger means is broadly designated by the numeral 8. Specifically this arrangement comprises a rigid vertical rod 10 of requisite length having an upper screw-threaded end 12 passing through a collar 14 provided therefor at the center of the ceiling bracket 16, the threaded end being secured in place by a nut 18. The bracket 16 is bolted at 20 to the ceiling or other stationary support means E. The lower end of the rod is provided with a T-coupling 22 one branch or end 24 ofwhich is connected to the lower end of the suspension rod 10. The horizontal branch 26 serves to accommodate a communicatively connected pipe 28 which is joined to a companion pipe 30 and which pipes are herein designated as the suction line. In actual practice the lower end of the line 30 will be connected to a source of suction and hair disposal collecting and trapping means (not shown). The suspension means is also characterized by a horizontally disposed freely movable tubular arm 32. One end 34 is suitably constructed and joined with the coupling branch 36 by way of a flexible and swivel-type coupling 38. Any suitable swivelling and coupling means may be provided here to support the arm 32. The righthand end portion 40 of the arm is constructed with an elbow or the like to accommodate a depending flexible hose 42 which is of an accordiontype and extensible and retractible and supports the clipper in the out-of-the-way position illustrated in FIG. 1.

3 The hair clipper is denoted at 44 and the hair intake or induction nozzle is designated generally at 46.

Taking up the nozzle, whether it be an attachment or built in as an original part of the clippers, it comprises a hair intake or induction nozzle of non-corrodible sheet metal or equivalent material the nozzle being denoted at 46. As seen in FIGURE thenozzle is generally elongated and rectangular in cross-section and comprises a top wall 48 having a,hole therein intermediate the forwardand rearward ends the hole designated at 50 and beingaligned with the oblique angled tapered neck 52 to which the cooperating end of the hose 42 is connected as denoted at 54 in FIG. 3. There is a bottom wall 56 parallel to the top wall and longitudinal side walls 58 prowided atthe rearward end of the nozzle with attaching flanges 60. The intake end of the nozzle is denoted at 62 and the opposite end at 64. The numeral 66 designates to mount the nozzle flatwise on the clippers to assume the cooperating position illustrated in the drawing. At this'point it will be noted that the body or handle portion of the clippers has an air intake passage 78 which registers I p with the hollow portion of the nozzle by way of a port or opening 80 as seen in FIG. 3. The idea here is that the suction also draws air through the passage 78 for cooling the handle and the motor (not shown) embodied herein. Attention is also directed to the oblique angled baflle 82 which is mounted-by way of an attaching flange 84. This baffle is located so that it directs the hair laden air through the neck 52 and into the hose in the manner shown in FIG. 3 by way of the arrows. The arrows also indicate cool .air coming through the passage 78 and entering the, nozzle and being drawn through the conduit in a manner to cool the motor.

The distance from the cutting blades 72 on the clipper 46 to the top edge of the induction nozzle intake 62, is i 'of an inch, and the induction nozzle is aflixed to the clippers to provide for such distance, with provision 66 for closing such distance to a lesser opening. The flexible hose is attached as shown so as to draw air through the clipper motor, thereby keeping the motor cool and. easier for the barber to handle.

Considered as an attachment the invention iscompact andhas an adjustable suction housing that fits any standard clipper and also. acts as a cooling means for the clipper motor. The connection is adjusted so asto allow the useof the clippers at any angle andv allows thebarber to use the clippers in his own way.

The foregoing is considered as illustrative only of the principles of, the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and. accordingly all suitable modifications, and

equivalents may be resorted to, falling within the scope of the invention as claimed.
